His kitten: Marked

Bright fuchsia eyes stared down at your panting figure in a loving manner. The devilish smirk never left Sebastian's lips, he couldn't be any more proud of himself because you finally permitted him to mark you as his and that's only the actual start of your relationship with him. Placing the seal on his mate was a very important task that had to be done so it could give Sebastian lots of abilities you'd be about to experience soon. It will also make other supernatural creatures know that you're his and his only.

The silver seal, he planted on your neck currently seemed more like a deep wound-scratch that created the symbol you would both share from now on. Of course, your demon didn't wound you, he would never dream of hurting you in any way. But unfortunately for you're just human, and the seal of eternal loyalty and devotion won't appear magically on you as Sebastian's did across his chest just a few minutes ago. It will need hours and your lover's care to make the toxic pain you are feeling right now go away.

But Sebastian swore to you, that this would be the first and last time you'd feel pain caused by him. Until the next morning, your wound will disappear completely and a facsimile seal, like his own, will be replaced on your soft delicate skin, successfully bounding you both forever.

Thin lines of hot tears were making their way down across your blushing cheeks. Soon you felt slender fingers gently caressing your skin. Sebastian laid his body on top of yours and used his one arm to be placed like a pillow under your head. "Oh, you poor little thing, Shhh, hush now my darling kitten. It's over" He whispered to your ear before his tongue licked gracefully your remaining tears away.

His free hand removed a few stray hairs off your forehead, but soon the cold feeling stopped when you felt his warm and soft lips placing tender kisses all over your face. "My love....my one and only companion~" He whispers once again still leaving kissies one after the other.

"Now... you will need my assistance, but you have to trust me and let me take care of you without any resistance or complaining, alright darling?' He questioned with a soft smile. He didn't wait for you to give him an actual answer as he lowered his head to your neck area and began to lick the bloody spot ever so carefully.

"Ah, it hurts...!" You protested and tried to push him away by placing your hands over his bare shoulders. That made him only chuckle at your pathetically adorable actions and pin your arms back to your sides. He wrapped his arms around you to make sure you'd stay in place and wouldn't try to move again.

"My dearest, please be a bit more patient and don't make any more noise. We were extremely lucky young master didn't hear your screams lately" The devil smirked mostly to himself and continued licking your wounded area. Fortunately, Sebastian was quite smart to plug everyone's ears before he was about to mark you as his own.

His saliva would help to heal your skin so your symbol will appear later on. "Don't keep yourself awake my love~ Just relax and let yourself submit to the pleasures of slumber" The sweet tone of his soft voice was like a lullaby to you.

Your eyelids felt heavier as time passed. "Now, sleep...sleep for me darling~" And so you did.

Your demon: Care for his mate

Your demon was over the kitchen, both hands quite busy preparing the first and most important meal you'd have for the day. Humming the very familiar lullaby he sings to you every night in hopes for you to have the sweetest of dreams.

He much prefers to cook without gloves when it comes to your meals or when touching you in general. His fingers brushed together as he added the pinch of salt here and there, it hurt yes since salt is a bit toxic for a demon's skin. But this one is willing to suffer the worst of agony if it means for you to be happy and protected. 

With the tray full of food in his hand, he was finally ready to go back to your room. However, his satisfied smile quickly dropped and a disgusted glare took its place across his devilishly handsome face. You see, your Husky dog was blocking the demon's way.

The dog sat right before Sébastian's tall figure with his tongue out while panting. Poor thing he couldn't resist the delicious smell of the goodies Sébastian had prepared especially for you.

"I strongly suggest you move aside right away. Such high-quality ingredients are not meant to be wasted by such a lowlife creature like yourself" He walked over to the door that led to the backyard. "Come now, get out and stay there until I'll be back" His cold tone along with the cruel glare of the demon's fuchsia eyes made your Husky let out a frightening whine and run outside.

Sébastian let out a deep sigh, expressing his hatred for the creature as he closed the door behind him, and then made his way upstairs to your room.

The door's cracking sound took your attention when you saw Sébastian walking inside while humming your lullaby. You watched as he placed the covered tray over the bed table.

With a soft smile and closed eyes, he embraced you with one arm while the other fixed the pillows of your bed. "There we go" He whispered and placed you gently with your back to rest against the fluffy pillows. When he made sure you were sitting comfortably the sinny tray was placed on your lap and with a graceful move Sebastian removed the lid, finally fully presenting your breakfast.

You smiled happily and pulled Sébastian for a hug. "Thank you Sébastian...for everything"

He chuckled and returned the hug. "Darling, you mustn't thank me at all. It's my duty and pleasure to take care of you in every single way" He explained softly as he placed a napkin under your chin while his other hand held the fork. "Now..." He put some food on the silver object and brought it close to your mouth. "Say ahh..."

You were about to tell him you could eat by yourself perfectly fine but his loving expression perverted you from doing so and just accepted his offer.

"That's it, what a good kitten you are~ From now on I will make sure you eat well at all times. I would never forgive myself if my precious mate went hungry. I am cursed to suffer starvation only to feed on a worthy soul, have a full stomach for 200 years, and then...go hungry again. I will never allow you to suffer like this. I will satisfy you in every possible way, if I couldn't take good care of my mate, then what kind of lover would I be?" Sébastian spoke joyfully while feeding you. 

"Will you be back tonight? You promised me we'd go out to celebrate my birthday which was yesterday" You managed to say before a piece of bread with butter and blueberry jam was put in your mouth. 

Your demon laughed softly and nodded his head in response. "Of course kitten how could I possibly forget? However, if things go well with the young master, I will come and pick you up after your lunch time and we may have more reasons to celebrate" 

"What do you mean exactly-" You were suddenly cut off guard when he left a soft peck on your lips and got off the bed with the tray of leftovers in one hand. "I won't spoil any more details of my surprise to you just yet but I am more than certain that is going to make both of us very happy indeed. Now you should get dressed and come downstairs when you're ready, we still have some more time left to spend together. Unless..." He leaned down to your level and whispered. "If you'd prefer some entertainment~" You felt his tongue give a slow and long lick to your ear. 

"I will be ready in a few minutes!" You almost shout as you get off the bed to grab the clothes that Sébastian had set out for you and enter the bathroom. 

Sébastian's shocked face couldn't remain more than a few seconds as he let an amused laugh escape from his lips. Such tricks never get old, especially when he gets to see such adorable reactions from you.

Your demon: A contract with limits

Ten minutes had passed and Sébastian didn't waste the chance to prepare your lunch and serve it to the kitchen's table, covered by a tray lid so it would remain warm for you to eat whenever you decide you want to. 

The demon walked over to the backyard door and let it open for your dog to come in. As he went back to clean some dishes he glared in disgust when your dog finally entered the house. His ears perked a bit when he caught the sound of your footsteps walking down the stairs. 

Alas, your attention was now completely focused on your dog who jumped with his front feet on your shoulders and licked your cheek, causing you to laugh and giggle the whole time. 

Sébastian swore that if it wasn't for your sake and only, this filthy creature would be thrown out to the streets. 

"Down Dingo, down now" You ordered the Husky with a steady tone and so he obeyed, making his way into the living room where his bed was. 

You turned to face your demon but your cheek made sudden contact against a bare chest which was Sébastian's of course. Then his arms snaked around your waist bringing you closer. You looked up to him and smiled sweetly. "Sébastian...."

Half-lidden reddish-orange eyes stared down at you lovingly. He cupped both sides of your face and began to rub your cheeks playfully.

"Hey...stop that!" You grabbed his larger hands to yours and looked up at him with a serious expression. "I don't want you to go"

He gave you a sad smile while stroking your hair. "Hopefully I won't be that long my love" His head leaned down to rub his nose against yours gently.

"But you always return at night time. What's that surprise you told me about? Please tell me" You spoke softly, due to the warm feeling of his lips against your forehead.

"I'll be back very soon. Don't forget to eat your lunch, yes kitten?" He purred to your ear and before you knew it he pulled you in for a rough-passionate kiss. And just like that, he was gone. Leaving you a flustered mess.

Sebastian sneaked into the mansion and started on his butler duties like every day. He went to the servants and let them know they'd be off their duties for today and they could take the time to rest. With breakfast and tea already made he entered his master's bedroom, he let the wheeled table aside for a moment and walked straight to the double window to yank open the curtains and let the sunlight fill the room.

Ciel's eyes cracked open and let a yaw out as his body slowly rise and stretched out his arms, now sitting on the bed with his back against the pillows.

"Good morning young master, did you sleep well last night?" Sebastian asked while filling his master's fine porcelain cup with freshly made tea, serving it to him gracefully. 

The boy's slender fingers curled around the cup's handle as he brought it close to his face and took a sip from the hot delicious liquid. "Don't act as if you care, it disgusts me. And your efforts to avoid the main topic of what we have to discuss are utterly pathetic. You sneaked away from the mansion...again" Young lord murmured the word 'again' under his teeth in an aggressive tone. "I've been told you ordered the rest of the servants to guard me and the estate from intruders when this was YOUR task in the first place. It's the 13th time you did so for this month and to be honest it started to get on my nerves. Tell me Sebastian do you plan to go against our contract?"

The butler's surprised expression slowly faded away, his eyes were closed and a devilish smirk took its place across his youthful face. "Not at all my lord, however, we have to make a serious conversion together about some changes we might have to make for our contract to remain and for the success of both yours and my goals" 

Ciel's single eye never left its gaze from Sebastian's reddish-orange ones. "What the hell do you-!"

"Now now sir, there is no need to raise your voice like that, I am more than certain we'll come to a proper agreement but I am afraid your today's lessons cannot wait. We can talk during your lunchtime if that would be alright with you of course"  The butler remained silent for a moment and waited patiently for his master to act.

Finally, Ciel looked away and let out a deep sigh. "Fine" He got off the bed and stood up straight while Sebastian was undressing and changed him into a fine new outfit. 

Some hours passed and now it was time for Ciel's lunch. The young lord was at his studies, reading and sighting up a bunch of papers until the familiar knock from the other side of the door took his attention. "Enter" He spoke coldly and let the papers down against the wooden surface of his office.

Sebastian walked into his master's studies and closed the door behind him. With slow steps, he approached Ciel's office, now standing right before him, and left the silver tray with the food in front of his master's view. "My lord" His tone was smooth and calm as he made a small bow with his hand placed over his heart. 

The boy held the fork between his fingers before he took a bite of rose beef and peals. "Speak and you better explain everything"

"As you wish sir, I've already told you about Miss Y\N and the relationship we developed during the 8 previous months"

"Don't tell me things I am already well aware of" Ciel commented back but stopped abruptly as his mind came up with a new possible situation, his hands hit hard to the office, and stood up from his seat. "What in the devil do want to say?!' He shouted out angrily.

Sebastian didn't lose the chance to get off his tie and unbutton his white shirt, his gloved hands grabbed both the shirt's sides exposing most of his chest where your shared silver seal would remain for eternity.  With closed eyes and a genuinely happy smile, he chuckled in amusement. His master's pure shocked face was more than entertaining to say the very least.

A shadow appeared on the boy's gaze as he lowered his head a bit. "BASTARD!" In a flash, the plate with his lunch was thrown across the demon's face. 

His face and hair were now all dirty and a complete mess, his hands pulled over his chest just in time to cover your shared seal from getting dirty. The demon let out a deep sigh. "Alas, I knew such a reaction couldn't be avoided from you master. However, you must calm yourself this doesn't change our contract. I will help you get your revenge and I will take your soul in exchange. My Y\N's case is different in all matters. You see, it turns out she was meant to be my mate and eternal companion. With this seal, I became responsible for her precious soul, so when the time came for her to pass away the reapers wouldn't have the right to take her soul to paradise or hell either. I will put her soul into new bodies as the centuries pass so, she will always remain alive and we'll be together forever. That was one of my promises to her. All I want to ask are some favors from you for both of the contracts between you, me, and her to work out in harmony" He explained calmly with his hands now behind his back.

Ciel was taking deep breaths in a desperate try to calm himself down. "What favors? And just to be clear, does she know about our contract?"

"Yes she does, I told her all about it. I couldn't hide the truth from my one and only mate after all. But fear not she's not going to give out our secrets, she's loyal enough as much as I am to her. About the favors, I wanted to ask...I would be more than grateful if you'd be so kind as to hire her as an employee here at the mansion. She's a very capable gardener and will be a great help to me compared to the mess those three are causing me all the time. I will be able to keep an eye on her and make sure she's safe. The second favor is that from now on I'd like to have 2 free hours during the day and a new bedroom I can share with her. That will be all my lord, I am sure this won't be any trouble compared to your generosity and kind nature"

"And what if I refuse all that nonsense you requested? Do not forget you acted behind my back and got against our contract no matter if you want to admit it or not"

Sebastian smiled mostly to himself and glanced back at his master with a confident gaze. "Then you have my wish for a happy future. Time was never my enemy and no matter how much time it will take me, I will find another tasteful meal to satisfy my stomach. You thought you could do whatever you desired with me, that I was your pawn, your tool to fight any block on your way and that's true but not without any limits. As a demon, I will never abandon my mate and I will stay by her side at all costs. The final decision is completely for you to take if you will agree or refuse my requests....so, what will you do, master?" The devil gave out a nasty smile, allowing his sharp teeth and fangs to be barely visible and his eyes to turn that pink-fuchsia of his.

You were eating peacefully your lunch, you spared a bit to Dingo as well when you heard the knocking on the front door. Sebastian who had already unlocked and made his way inside with the extra pair of keys you had given him walked towards you and lifted you from your seat to his arms. "My surprise to you awaits, shall we go now kitten?" He questioned with his forehead against yours.

Hi could I request headcanons of Sebastian with a physically clingy s/o?

Here are the headcanons you asked for. Hope they are to your liking.

✿ Sebastian thinks your clingy behavior is simply adorable.

✿ Honestly, he's no better since he has the need to touch you at least once or twice every one hour.

✿ He doesn't know what to do with himself when he's not cuddling you.

✿ But seven minutes of a no-stop loving make out session while sitting on his lap would do nicely.

✿ If he could satisfy your desire for physical affection all the time, believe me, he would be more than happy to do so however there's his butler aesthetic and the fact he has to serve the young master in the middle that prevents him from fulfilling that endless need of yours.

✿ When he has his two free hours he's all yours.

✿ During this amount of time, he takes you to the hidden spot he created just for the two of you deep in the gardens and takes advange of all this free time he has to hug you, treat your hands, cheeks, neck, jaw, forehead, and lips with smoochies and gentle nibs.

✿ These two hours and the nighttime are simple the best cause you get to have your demon completely focused on you and your need for affection and adoration.

✿ You love bath time too, because it's Sebastian who's usually bathing you, treats your skin with the best of the best care and when he washes and brushes your hair it feels just 'ahhhh~".

✿ When you want affection though and he can't provide you with it mostly because he's working at this time he will simply take down to his one knee right before you and take your hands gently to his larger owns and give them a sweet long kiss while staring at you with a sorry gaze and a sad smile.

✿ "Not now my darling kitten" He will whisper smoothly and turn back to what he was doing.

✿ The second time or the third you're going to insist and keep behaving like this he's going to break the distance between you both and wrap his arms around your waist in a tight yet warm embrace.

✿ His lips will make contact with your forehead and start leaving kisses one after the other.

✿ "My love, I thought I told you to wait after young master's bedtime for me to give you affection, didn't I?" He caresses the side of your face with his white-gloved hand while staring seriously down at your slightly confused face.

✿ Unfortunately, you kept doing this more and more often most of Ciel's annoyance. Sebastian was a bit upset but then again it might be his fault he wasn't giving you enough affection in the first place. Or the solution would be if he'd give you more than you can handle...

✿ So the next time you demanded his affection, without any words he lifted you up and placed you over his shoulder, giving your butt some gentle pats along with a dark chuckle that let you know you were in trouble.

✿ It was night that Sebastian had plugged everyone's ears so no one but him could hear your screams of pleasure and loud moans.

✿ The next day Sebastian informed his master that for a reason you were hardly able to walk out of your and Sebastian's shared bedroom and so you stayed in bed all day, trying to get your strength back after such a long night with your loving devil.

✿ After that, you would think twice before you'd ask Sebastian for affection when it's not the right time.
